Makhalidwe a wollastonite

Wollastonite ndi ya mtundu umodzi wa miyala ya silicate, yokhala ndi formula ya molekyulu Ca3 [Si3O9], ndipo nthawi zambiri imakhala ngati ulusi, singano, ma flakes, kapena ma radiation. Wollastonite nthawi zambiri imakhala yoyera kapena yoyera ngati imvi, yokhala ndi kuwala kwina. Wollastonite ili ndi mawonekedwe apadera a kristalo, motero ili ndi kutchinjiriza bwino, mphamvu zamagetsi, komanso kukana kutentha kwambiri komanso nyengo. Makhalidwe amenewa ndi omwenso amaika patsogolo ntchito ya wollastonite pamsika.

1. Zophimba
Wollastonite, yokhala ndi mphamvu yowonjezereka yowunikira, mphamvu yophimba mwamphamvu, komanso mafuta ochepa, ndi chida chodzaza bwino zophimba nyumba, zophimba zoteteza dzimbiri, zophimba zosalowa madzi komanso zosapsa moto. Imatha kusintha bwino mphamvu ya makina a zophimba monga kukana kusamba, kukana kuzizira, kukana ming'alu, ndi kukana kupindika, komanso kukana dzimbiri, kukana nyengo, komanso kukana kutentha. Ndi yoyenera kwambiri popanga utoto woyera wapamwamba komanso utoto wowonekera bwino komanso wowonekera; Popanda kukhudza kuphimba ndi kusambitsidwa kwa zophimba, wollastonite imatha kusintha 20% -30% titanium dioxide mu dongosolo la utoto wa latex wamkati, kukweza pH ya dongosolo, ndikuchepetsa mtengo wopanga zophimba.

2. Zoumbaumba
Wollastonite ingagwiritsidwe ntchito kwambiri pazinthu zadothi monga matailosi opakidwa utoto, zoumba za tsiku ndi tsiku, zoumba zaukhondo, zoumba zaluso, zoumba zapadera zosefera, zoumba zadothi zadothi, zoumba zadothi zamagetsi zoteteza kutentha kwambiri, zoumba zadothi zopepuka, ndi zoumba zadothi zamagetsi. Ikhoza kusintha kuyera, kuyamwa madzi, kufutukuka kwa hygroscopic, komanso kukana kuzizira mwachangu ndi kutentha kwa zinthu zadothi, zomwe zimapangitsa kuti zinthu ziwoneke bwino komanso zowala, ndi mphamvu yowonjezera komanso kukana bwino kupanikizika. Mwachidule, ntchito za wollastonite mu zoumba zadothi zimaphatikizapo: kuchepetsa kutentha kwa kuwombera ndikufupikitsa nthawi yowombera; Kuchepetsa kuchepera kwa sintering ndi zolakwika zazinthu; Kuchepetsa kufutukuka kwa hygroscopic kwa thupi lobiriwira ndi kufutukuka kwa kutentha panthawi yowombera; Kukweza mphamvu yamakina ya chinthucho.

3. Rabala
Wollastonite ikhoza kusintha titanium dioxide yambiri, dongo, ndi lithopone pogwiritsa ntchito mphira wopepuka, zomwe zimapangitsa kuti zinthu zikhale zolimba komanso kukonza mphamvu yophimba zinthu zoyera, zomwe zimapangitsa kuti zinthu ziwoneke bwino. Makamaka pambuyo pa kusintha kwa organic, pamwamba pa wollastonite sikuti pamakhala lipophilicity yokha, komanso chifukwa cha ma bond awiri a mamolekyu a sodium oleate, imatha kutenga nawo mbali mu vulcanization, kuwonjezera kulumikizana, komanso kuwonjezera mphamvu yolimbitsa.

4. Pulasitiki
Kukana kwambiri, kusasinthasintha kwa dielectric, komanso kuyamwa mafuta pang'ono kwa wollastonite kumapangitsa kuti ubwino wake mumakampani opanga pulasitiki uwonekere bwino kuposa zinthu zina zopanda chitsulo. Makamaka pambuyo posintha, kugwirizana kwa wollastonite ndi mapulasitiki kumawonjezeka kwambiri, zomwe zingathandize kukonza bwino mawonekedwe a pulasitiki ndikuwonetsetsa kuti kutentha kuli bwino, dielectric yochepa, kuyamwa mafuta pang'ono, komanso mphamvu yayikulu yamakina ya chinthucho. Zingathenso kuchepetsa mtengo wa chinthucho. Wollastonite imagwiritsidwa ntchito kwambiri popanga nayiloni, yomwe ingathandize kulimbitsa mphamvu yopindika, kulimba, kuchepetsa kuyamwa kwa chinyezi, ndikuwonjezera kukhazikika kwa mawonekedwe.

5. Kupanga mapepala
Wollastonite ili ndi refractive index komanso kuyera kwambiri, ndipo monga chodzaza, imatha kuwonjezera kuonekera ndi kuyera kwa pepala. Wollastonite imagwiritsidwa ntchito popanga mapepala, ndipo netiweki ya ulusi wa chomera cha wollastonite yomwe imachokera imakhala ndi kapangidwe kakang'ono kwambiri, komwe kumathandizira kuti inki igwire bwino ntchito ya pepala. Nthawi yomweyo, chifukwa cha kusalala bwino komanso kuchepa kwa kuwonekera bwino, imawonjezera kusindikizidwa kwa pepala. Wollastonite imasokoneza kumangidwa kwa ulusi wa zomera, zomwe zimapangitsa kuti zisakhudzidwe ndi chinyezi, kuchepetsa hygroscopicity yawo ndi kusintha kwawo, ndikuwonjezera kukhazikika kwa pepala. Malinga ndi zofunikira papepala, kuchuluka kwa wollastonite komwe kumadzazidwa kumasiyana kuyambira 5% mpaka 35%. Kuyera, kufalikira, ndi kusinthasintha kwa ufa wa wollastonite wophwanyidwa bwino kwambiri kwasintha kwambiri, komwe kumatha kulowa m'malo mwa titanium dioxide ngati chodzaza mapepala.

6. Zoteteza zitsulo
Wollastonite ili ndi mawonekedwe otsika osungunuka, kukhuthala kochepa kwa kutentha kwambiri, komanso magwiridwe antchito abwino oteteza, ndipo imagwiritsidwa ntchito kwambiri mu slag yoteteza yopitilira. Poyerekeza ndi slag yoteteza yosakhala ya wollastonite, slag yoteteza yochokera ku wollastonite ili ndi zabwino izi: magwiridwe antchito okhazikika komanso kusinthasintha kwakukulu; Ilibe madzi a kristalo ndipo imataya pang'ono pa kuyaka; Ili ndi mphamvu yayikulu yoyatsira ndi kusungunula zinthu zomwe zikuphatikizidwa; Ili ndi kukhazikika kwabwino kwa njira; Ili ndi ntchito zabwino kwambiri zoyendetsera zitsulo; Yaukhondo kwambiri, yathanzi, komanso yosamalira chilengedwe; Imatha kusintha mtundu ndi magwiridwe antchito a kupanga slag yopitilira.

7. Zinthu zokangana
Wollastonite ili ndi mphamvu zofanana ndi singano, mphamvu yotsika yotambasula, komanso kukana kutentha kwambiri, zomwe zimapangitsa kuti ikhale m'malo abwino kwambiri a asbestos yaufupi. Zipangizo zokangana zomwe zimakonzedwa posintha asbestos ndi wollastonite yokwanira kwambiri zimagwiritsidwa ntchito makamaka m'magawo monga ma brake pads, ma plug a valve, ndi ma clutch agalimoto. Pambuyo poyesa, magwiridwe antchito onse amakhala abwino, ndipo mtunda woyimitsa ndi nthawi yogwirira ntchito zimakwaniritsa zofunikira. Kuphatikiza apo, wollastonite imatha kupangidwanso kukhala ubweya wa mchere wofewa komanso zinthu zosiyanasiyana zolowa m'malo mwa asbestos monga kutchinjiriza mawu, zomwe zingachepetse kwambiri kugwiritsa ntchito asbestos ndipo ndizothandiza poteteza chilengedwe ndikuwonetsetsa thanzi la anthu.

8. Maelekitirodi owotcherera
Kugwiritsa ntchito wollastonite ngati chophikira cha ma electrode olumikizirana kungathandize kusungunula ndi kupanga slag, kuchepetsa kutulutsa madzi panthawi yolumikizirana, kuchepetsa kupopera, kukonza kusinthasintha kwa slag, kupangitsa kuti msoko wa weld ukhale woyera komanso wokongola, komanso kulimbitsa mphamvu ya makina. Wollastonite ingaperekenso calcium oxide kuti ndodo zolumikizirana zituluke, pomwe ikubweretsa silicon dioxide kuti ipange slag yambiri ya alkaline, yomwe imachepetsa ma pores oyaka ndi zolakwika zina pamalumikizidwe. Kuchuluka kwa zowonjezera nthawi zambiri kumakhala 10-20%.
